3-Hydroxyphenylboronic acid (CAS 87199-18-6)

Application and positioning

The meta-hydroxy isomer avoids the boron chelation of the ortho form while still leaving a phenol handle after coupling. It is used for 3-hydroxybiaryls, including resorcinol-derived fragments and polyphenol intermediates. Laurand supplies it from audited Chinese producers in kilogram to multi-tonne lots, with the documentation your market requires.
